The Eddy-S4 Device Server Development Board features a socket for the Eddy-CPU-V2.5 AT91SAM9G20 (ARM9) CPU Module with 8MB Flash and 32MB SDRAM (module is not included). With two 10/100Mbps Ethernet ports and 4x RS232 or 4x RS422/485 ports, it provides a powerful platform for developing your serial device server application. The serial ports use RJ45 connectors, so you can use a standard Ethernet cable with an Ethernet-to-DB9 adapter to connect your serial devices. The Eddy-CPU module, Ethernet cable and DB9 adapters are available as optional accessories at the bottom of this page. The picture shows an Eddy-CPU module installed for illustration purposes only.

Two versions of this board are available:

Eddy-S4-RS232: with 4x RS232 ports

Eddy-S4-Combo: with 4x RS422/RSS485 ports

You can select your desired port configuration from the drop-down option menu at the bottom of this order page.

We also offer the Eddy-S8 model, which offers 8x RS232 or 8x RS422/RS485 ports.

Using the optional plug-on Eddy-WiFi module you can easily add wireless capability to this board (the WiFi module plugs onto the CPU module, which also must be purchased separately).
